Be it known that I, STEPHEN INMAN, of Rockford, in the county of Winnebago, and- State of Illinois, have invented a-new and useful-.Improvement iu Brick- Moulds; and I do hereby declare that the following isa full and exact description of the same, reference This invention relates to that 'class of brick-moulds which is providedwith a Iseries of followers fin its i divisions, which "are sim'nltaneously operated for the purpose of expelling the newly-formed bric k; and conffsists mainly in the arrangement of .the levers for operating the followers.. i

i The detailsof construction and manner of operation will be fully described hereinafter. i

In the drawings--` .l

Figure 1 represents aplan view, and Eigures 2,-"3, and 4, sectional elevations of tlie mould at d iiferent points,as indicated in fig. :1. i

To enable others skilled in 4the art to make and use my invention, I will now, proceed to constr'uctioand operation; A represents a-brickeinould, which the divisions a airain the usual Well-known manner. 'In'each of thesedivisions is placed a follower, which is held'and operated by means of tlie `cross-rods b b,

which. are attachedthereto 'in any, suitable manner that will permit the necessary movement.

The .outer endsof` these`crossrods are rigidl'y'at-4 in the drawings. i

`The. maso care had `m position by any suitable means, it being essential, however, thatV they be perl mitted to revolve freely in their bearings.

By giving these rods aA partial revolution-,the free ends'of the cross-(rods b will ,of course, be caused to describe thearc which may be arranged in any suitable manner therefor. I preferably provide them with larmsrl d, which have their bearing upon one of the partitions of the being had tothe accompanying drawings, and to the v letters of reference marked thereon.

mould, `'as shown, the partition being recessed, `in order that the lever may not project beyond the surface line of the mould.

The shortarm of the' levers is slotted to receive the l .ends ofthe rods di, by means of which connection is made With.the rodsG C.

The long arm of the levers extends to the ends of the-nioulchfas shown, and isprovided with the 'handles di d, to enable it to be easily grasped. r

It will be observed that each ofthe partitions, crossed by the levers, is recessed to receive them, in order that that the lower surface of the moulds may be free fromprojectioi-is when itis inserted into the machine. In 'order that the levers `may be securely-fixed in place when not irl-operation, I provide the springcatches..ewhich engage with catches d d upon the `handles ofthe levers, as shown.

The operation is as follows: y The mould isnserted in the machine, and tilled in the usual manner, the levers D, of course, being perfectly secured in place. When filled, it is `carried to the drying ground and inverted.

sprung back from the levers by the fingers of the operator, and the latter are operated, and the brick thereby expelled. 4 Having thus fully described rny invention,

What I claim as new, and desire to secure by Letters Patent, is-' `l. The `combination of the longitudinal turning rods `O and arms 71, with the centrally-arranged lever Dand rods all, as described, for the purpose set forth.
